February 13, 20197 yr Hey all, It would seem I need this in my basement and a drainage channel around it. Seems rather expensive! so it's just to provide height (a raft) for the drain. Googled but can't find an equivalent (slotted!). Could I not just use some cheaper XPS variant??? Cheers Edited February 13, 20197 yr by pocster
